Abstract
Methods and systems for protecting websites from cross-site scripting are disclosed. A request for a web page comprising a web page element is received from a client. It is determined if the web page comprises a data integrity token for the web page element. It is also determined if a value of the data integrity token matches an expected value. If the web page comprises the data integrity token and if the value matches the expected value, the web page comprising the web page element is sent to the client. If the web page does not comprise the data integrity token or if the value does not match the expected value, a protective operation is performed.
